| Abstract: | The thermal fatigue behavior of white cast iron with different quantity of deformation has been investigated in the paper. The results show that eutectic carbide is the main location and passage for initiation and extension of thermal fatigue crack, approving that the more serious the carbide breaks, the higher thermal fatigue resistance of the white cast iron will be and the thermal fatigue fracture belongs mainly in cleavage fracture. |
